5. Energy saving and optimum operation
INFORMATION
• Even if the unit is turned OFF, it consumes electricity.
• When the power turns back on after a power break, the
previously selected mode will be resumed.
CAUTION
NEVER expose little children, plants or animals directly to the
airflow.
WARNING
Do NOT place objects below the indoor and/or outdoor unit that
may get wet. Otherwise condensation on the unit or refrigerant
pipes, air filter dirt or drain blockage may cause dripping, and
objects under the unit may get dirty or damaged.
NOTICE
Do NOT use the system for other purposes. In order to avoid
any quality deterioration, do NOT use the unit for cooling
precision instruments, food, plants, animals, or works of art.
WARNING
Do NOT place a flammable spray bottle near the air conditioner
and do NOT use sprays. Doing so may result in a fire.
Observe the following precautions to ensure the system
operates properly.
• Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.
• Ventilate often. Extended use requires special attention to
ventilation.
• Keep doors and windows closed. If the doors and windows
remain open, air will flow out of your room causing a decrease
in the cooling or heating effect.
• Be careful NOT to cool or heat too much. To save energy, keep
the temperature setting at a moderate level.
• NEVER place objects near the air inlet or the air outlet of the unit.
Doing so may cause a reduced heating/cooling effect or stop
operation.
• Turn off the main power supply switch to the unit when the
unit is NOT used for longer periods of time. If the main power
supply switch is on, the unit consumes electricity. Before
restarting the unit, turn on the main power supply switch 6
hours before operation to ensure smooth running.
• Condensation may form if the humidity is above 80% or if the
drain outlet gets blocked.
• Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling. Notice that
it may take some time for the room temperature to reach the
set temperature. Consider using the timer setting options.
• Adjust the airflow direction to avoid cool air from gathering on
the floor or warm air against the ceiling. (Up during cooling or
dry operation to the ceiling and down during heating operation.)
• Avoid direct airflow to room inhabitants.
• Operate the system within the recommended temperature range
(26~28°C for cooling and 20~24°C for heating) to save energy.
6. Maintenance and service
6-1 Overview: Maintenance and service
The installer has to perform yearly maintenance.
WARNING
• The refrigerant inside the unit is mildly flammable, but normally
does NOT leak. If the refrigerant leaks in the room and comes
in contact with fire from a burner, a heater, or a cooker, this
may result in fire, or the formation of a harmful gas.
• Turn off any combustible heating devices, ventilate the room,
and contact the dealer where you purchased the unit.
• Do NOT use the unit until a service person confirms that the
part from which the refrigerant leaked has been repaired.
• Do NOT pierce or burn refrigerant cycle parts.
• Do NOT use cleaning materials or means to accelerate the
defrosting process other than those recommended by the
manufacturer.
• Be aware that the refrigerant inside the system is odourless.
• The appliance shall be stored in a room without continuously
operating ignition sources (example: open flames, an
operating gas appliance or an operating electric heater).
